Answer:
15.4%
Step-by-step explanation:
Calculate the volume of both containers.
The volume (V) of a cylinder is calculated as
V = πr²h ( r is the radius and h the height )
= π × 10² × 11 = 1100π ft³
= π × 7² × 19 = 931π ft³
Subtract volume of B from volume of A to find quantity left in A
quantity left in A = 1100π - 931π = 169π ft³
To calculate the percentage left in A after B has been filled
× 100%
= × 100%
= × 100%
= 15.4% ( to the nearest tenth )

Answer:
It will take 6 minutes by Ashley and Emma to read the same amount of pages.
Step-by-step explanation:
Let in 't' minutes Ashley and Emma will read the same amount of pages.
If Ashley can read one page in a minute then she can read the number of pages in t minutes = 1×t =t
If she starts from page 1 then after time 't' she will be at the page = (t + 1)
Similarly, if Emma takes 3 minutes to read the amount of pages = 1
Then she can read amount of pages in t minutes =
If Emma starts from page 5 then after t minutes she will be at the page =
If both have read the same amount of pages then,
t = 6 minutes
Therefore, it will take 6 minutes by Ashley and Emma to read the same amount of pages.
